I went with ALA who beat the cheapest quote. £192 for 4 years cover instead of £350 for 3 years cover which is what VW was trying to sell me. Don't let VW put you off. The salesmen was trying to tell me that you can't get 4 year GAP insurance and he's seen instances where these companies don't pay out.
Anyway, I absolutely love the car. Just brilliant. Well worth the wait!
